JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 496,174, dated April25, 1893.

Application filed January 5, 1893. Serial No. 457,371. (No model.)

To all whom it may concern..-

Be it known that I, SYLvEsrER T. F. STER- IOK, acitizen of the UnitedStates, residing at Gaithersburg, in the county of Montgomery and Stateof Maryland, have invented certain new and useful Improvements in Journal- Boxes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in journal boxes and it consistsin the construction and arrangement of parts hereinafter described anddefinitely pointed out in the claim.

The aim and purpose of the invention is the provision of an improvedjournal box and rollerbearin g having in connection therewith suitablemeans for lubricating the bearings and collecting the scale and otherforeign matter. I attain these objects by the construction illustratedin the accompanying drawings wherein like letters of reference indicatelike parts in the several views and in which- Figure l is a front viewof the box. Fig. 2 is a longitudinal section thereof showing the rollersin elevation. Fig. 3 is a cross section through the line a mof Fig. 2and Fig. 4 is an elevation of a modified form.

In the drawings A represents the box having the hangers B, and 0represents the shaft or axle. The box A is divided into two sections a.a which are united by the bolts a passing through apertures at thecorners of the box, other forms of uniting the sections may however beemployed. On the inner face of the box at its center is an inwardlyprojecting rib 0, having the usual curved or rounded edge. The oppositeends of the box are formed with annular grooves E, extending into thesame to points below the plane of the bearing face of the box, which islocated between the grooves and rib.

F are the rollers having the usual groove f at their centers in whichthe rib O engages. The journals f of the roller are placed in suitablebearings formed in the spacing rings G. Heretofore in boxes of thisnature it has been found that the end play of the rollers is practicallyprevented by the central rib which works in the grooves formed in therollers and the spacing rings are required to be secured in position bythe cross bolts or rods, which are designated in the accompanyingdrawings at g. A cage is thus formed which owing to the mounting of therollers in the rings, has a tendency to slightly move longitudinally andthereby at times cause the cage to twist carrying the rollers out ofalignment with the shaft. To overcome this objection, I form the groovesE in the box, and construct the rings so that their peripheries willextend into the grooves'beyond the rollers, the width of the rings beingslightly smaller than that of the grooves so that they may move freelytherein during rotation butall wabbling or side play is prevented. Thecage is thereby held in perfect alignment and the rollers always heldparallel with the shaft.

To provide means for thoroughly lubricating the bearings of the rollsand the peripheries of the rings I form at the opposite ends of the boxin the under section, oil pockets H. These pockets occupy positionsadjacent to the peripheries of the rings their inner Walls terminatingdirectly below the rolls and their outer walls terminating at pointscentral of the grooves E, the inner Walls of the grooves at these pointsbeing omitted, the rings moving partly in the grooves and partly in theoil pockets, thereby forming feeders which carry the oil, with whichthey contact, to the bearings. These pockets also serve to receive thescale or sediment caused by wear, accumulated dust, &c., therebyrelieving the rollers of such wearing material.

In supplying the oil the sections may be separated or suitable fillingvents may be formed in the walls of the box.

In Fig. 4 I have shown the box applied to railway car axles in whichcase one end would necessarily be closed.

I am aware that minor changes in the construction and arrangement of theparts can be made and substituted for those herein shown and describedwithout departing from the nature and principle of my invent-ion.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent, is-

A roller bearing consisting of a box having annular grooves at itsopposite ends, a central inwardly extending rib, and oil pockets formedin the lower portion thereof at opposite ends, with which the groovescommunicate, a seriesof rollers having central peripheral grooves,rings, working in the annular 1o groove of the box and pockets and inwhich the rollers are journaled and rods entering the ringsat pointsbetween the rolls, substantially as described.

In testimony whereof I alfix my signature in presence of two witnesses.
